Of course integrated amps can be high end. I put a similar thread up a couple of months ago and got slapped down for suggesting they could match a top of the range pre and monoblocks. Well perhaps an integrated can't match the very best separates, that does'nt mean they are not High End. It seems manufacturers are putting more effort into integrated amps. not all, CJ for example does'nt have a current integrated.
I have gone from separetes to 2 good integrated amps. The first is the Viva Solista, mentioned by Larri, an 18 watt 845 SET . Certainly makes the best sound I have had out of my system, with drive and dynamics belying the 18 watts. If the dam thing did'nt keep blowing capacitors and it did'nt cause the streetlights to dim , with the power it draws, it would be perfect. The other is a Lavardin IT, which fully deserves its reputation.
As others have mentioned, there are so many other good products, from Jadis, the Musical Fidelity KW, Accuphase, VAC, never mind the plethora of excellent new, high value Chinese amps. I can't remember there being better choice
